Replace the SignalR-circuit-race-prone Playwright component tests for GameEdit, Settings, metadata, profile, roles and users with in-process bUnit component tests. Keep a thin Playwright smoke layer for the true E2E paths (login, admin navigation/routing, first-time setup, game import) that bUnit cannot cover.
